Definitions

  • the present invention concerns a seat comprising a seat back, a cushion, a pivoting handle mounted on one of the lateral sides of the seat back and adapted to cause the seat back to tilt onto the cushion from a raised position, a rotary plate fixed under the cushion, and a pivoting lever affixed to the rotary plate and adapted to cause the cushion to rotate on itself with the seat back in the raised position.
  • It relates more specifically to a seat of this type mounted as a motor vehicle front seat.
  • the purpose of the invention is thus to propose a seat of the type mentioned above which allows the passenger to have a large accessibility to the rear seats of an automobile while being easy to manipulate.
  • an object of the invention is a seat, in particular for an automobile, comprising a seat back, a cushion, a pivoting handle mounted one of the lateral sides of the seat back and adapted to cause the seat back to tilt onto the cushion from a raised position, a rotary plate fixed under the cushion and a pivoting lever fixed to the rotary plate and adapted to cause the cushion to rotate around the axis of rotation of the rotary plate with the seat back in the raised position, characterized in that it comprises means to cause the pivoting lever to rotate immediately after the pivoting of the handle so as to obtain a rotation of the cushion around the axis of rotation of the rotary plate immediately after the seat back has been tilted onto the cushion.
  • the means are comprised of a cable having one of its ends affixed to the rear part of the seat back and the other end affixed to the pivoting lever;
  • the cable is housed in a sheath
  • the seat consists of tubes affixed to the lower part of the rotary plate, which extend across it, the ends of these tubes being adapted to be affixed to a floor such as a floor of an automobile;
  • the axis of rotation of the rotary plate is offset relative to the axis of the cushion.
  • the invention also concerns a motor vehicle equipped with at least one seat described above, preferably mounted as a front seat.
  • FIGS. 1 to 4 show:
  • FIG. 1 a schematic side view of a front seat of an automobile according to the invention
  • FIGS. 2 a and 2 b two detailed side views of a part of the seat back according to the invention in a raised position and in an intermediate position of the tilting of the seat back towards the cushion, respectively;
  • FIG. 3 a detailed top view of the rotary plate according to the invention.
  • FIG. 4 a top view of the seat according to the invention, the seat back being in an intermediate position tilted on the cushion, the latter having been turned on itself by an angle of 45° relative to the fixed driving position.
  • FIG. 1 shows a front seat of an automobile wherein access to the rear seats is very limited while the seat back 2 is in a raised position, i.e., approximately vertical to the cushion 3 , and when the cushion is in a driving position, i.e., fixed and approximately parallel to the lateral side of the vehicle body, which is not shown.
  • This front seat 1 comprises, in a manner that is itself known, a handle 21 pivotally mounted on the lateral side 22 of the seat back 2 closest to the front door, which is not shown, when the cushion is in the driving position.
  • It also comprises a rotary plate 4 affixed below the cushion 3 and having an axis of rotation (P) that is offset from the median axis (C) between the front end and the back end of the seat cushion by a distance d that is sufficiently large to increase the interior living space when the seat back 2 faces the rear seats of the vehicle and that is sufficiently small so that the seat back in the raised position does not come into contact with other elements of the vehicle when the cushion turns, such as the corresponding lateral support of the car body or the dashboard.
  • P axis of rotation
  • C median axis
  • the rotary plate 4 As to the rotary plate 4 , it comprises, in its lower part, two tubes 41 , 42 that are affixed by means of screws, which are not shown, and that extend transversely across the plate along two of its sides.
  • the ends 410 , 420 of these tubes are affixed to two side rails 43 , also by means of screws, which are not shown.
  • the side rails 43 are themselves affixed directly to the floor of an automobile, also by means of screws.
  • a pivoting lever 44 is fitted tightly in a flexible, curved tab 45 arranged in front of the rotary plate 4 .
  • the rotation of this lever 44 towards the cushion causes, in a manner itself known, a rotation of the cushion 3 around the axis of rotation of the rotary plate (P) with the seat back 2 in the raised position.
  • the seat 1 comprises a cable 5 having one of its ends 51 fixed in a clamp 52 .
  • This attachment of the end 51 of the cable 5 in the clamp 52 can be done by any means available to the person of the art. This can include, for example, a screw going through the clamp that presses the end 51 of the cable 5 against the inside of the recess made in the clamp 52 in which the cable is housed.
  • the clamp 52 is itself affixed to the rear part of the seat back 2 by welding.
  • the cable 5 is arranged in a protective sheath 53 that prevents damage to the cover of the seat 1 and that has a stop 531 against the rear of the seat back 2 .
  • the other end 54 is itself fixed into an attachment clamp 55 welded to the pivoting lever 44 at the end 441 opposite the one 442 on which the operating knob of the lever 443 is placed.
  • the entire central part of the cable 5 is itself arranged along the seat 1 below the cushion 3 and along the upper part of the rotary plate 4 , the protective sheath 53 being affixed to the rotary plate 4 by means of attachments, which are themselves known, and which are not shown.
  • the length of the cable 5 is judiciously selected so as not to disturb the complete rotation of the cushion 3 around the axis of rotation of the rotary plate 4 , i.e., in the order of 180°.
  • This rotation corresponds to an orientation of the front seat such that the seat back 2 faces the rear seats of the vehicle, with the rear of the seat back facing the dashboard of the vehicle.
  • the passenger can thus, without difficulty, maneuver the seat 1 with the seat back 2 tilted down, and easily orient it towards the outside, for example, at an angle of rotation ⁇ between 45 and 135° (the angle of rotation here is the angle measured from the initial position of the seat 1 , i.e., fixed with the rear of the seat back facing the rear seats) as shown in FIG. 3 .
  • Accessibility to the rear seats is thus greatly improved since the passenger can easily orient the front seat 1 when he gets into the vehicle with the seat back 2 tilted down, without having to manipulate other elements.
  • the embodiment mode which has just been described is very advantageous to the extent that it makes it possible to obtain the desired kinematics while adding a minimum number of parts that do not change the structure of the seat.
  • the additional cost caused by the installation of the cable according to the invention is thus very low.
